The Integrated Amplifier which corresponded also to
CDV and carries an image termination. It has nine voice and an input/output
terminal of four images.
In order to send out without leaving the
quality of CDV, highly precise-ization of a video chain is pursued.
Image amplifier has adopted the perfect discrete stream composition by the independent
substrate which carried out the separation to the audio system. Moreover, a
stream-composition part thinks as important and selects the property of a video
signal band carefully, it excels in a substrate at a RF property, and the
vibration proof effect is also using the high paper polyesters substrate.
Moreover, between input/output terminals was connected with the video-system
amplifier board by the shortest distance by the newly developed video-system
short circuit, the cross interferencee was eliminated thoroughly, and the
crosstalk is improved to the RF area which also amounts to 3MHz - 4MHz.
Furthermore, CDV, VCR, etc. supplied the power source independently to each
amplifier of the image, and the differential input direct-drive is realized.
The audio and the video system were used as the full independence power
source, and the cross interferencee is eliminated from the power-source part.
Moreover, the Mie diffusion type transistor excellent in large-current drive
capacity is adopted as a power device.
The frequency curve of the inside
bass region was controlled and two positions of audio-video sound switchpoints
which raise a presence are equipped.
audio video SOUND 1 raises super-low-pass one of 50Hz or more, and it is reproducing the presence of music sources, such as the live.
audio video SOUND 2 raises the inside low-pass below "200Hz - 300Hz", and it can enjoy movie software in a powerful sound.
compact-disk direct switchpoint which can use the input signal of
compact-disk-1 in the shortest path of volume -> flat amplifier -> power
amplifier is carried.
The copy switchpoint which can do dubbing of a
tapes 1->2 in one-touch is carried.
The rear panel is equipped with
the selector which can carry out the stereo / monophonic change of the voice
input/output of VCR2.
The speaker selector which can turn on and off the
speaker outputs 1/2 independently is equipped.
Main product lines used
the OFC (oxygen free high conductivity copper) line, and the gilding termination
is adopted as compact-disk-1/2, and a phone input.
Moreover, the using part,
such as adopting a copper plating screw as all the screws, throws in the part
chosen by the severe hearing.
